kring_c14,

If this is an exam, and you can't understand it, then somewhere the communication process between you and your professor has broken down, and you need to re-establish that contact.

As for us here at PF, we require that you show some evidence of effort before we help you. Please, for your own sake, start by talking to your professor.
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
